DM package does not read context member correctly when 2 or more member IDs have same desription

Dear Experts,

I pass my context values to my script logic, however in case 2 different member ID have same description for  a dimension as you can see in attached file, system does not read selected one in EPM Context Member, it assigns first ID to DM prompt screen found in master data at first row which has the same description with the selected member in EPM Context.

I have searched for an OSS note or customizing note, I could not find any valuable information. Any idea?????

Second question: When I click EPM-Context Options, under 2. tab "Context Lock", I see my dimension members' descriptions under "selected dimension members" tab (2. column), is it possible to change here only to show ID?

Thanks and Regards,
